After you sign up at ForgeRock, you can also login to the Wiki and the issue database to follow what is happening with the project. If you have questions regarding OpenDJ which are not answered by the documentation, there is a mailing list which can be found at https://lists.forgerock.org/mailman/listinfo/opendj where you are likely to find an answer. You can also make suggestions regarding updates at the documentation mailing list (https://lists.forgerock.org/mailman/listinfo/docs). You can join the IRC discussion in the #opendj room at irc.freenode.net. The Wiki has information on how to check out OpenDJ source code. There is also a mailing list for OpenDJ development that can be found at https://lists.forgerock.org/mailman/listinfo/opendj-dev. Should you want to contribute a patch, test, or feature, or want to author part of the core documentation, first have a look on the ForgeRock Community page at how to get involved.
